ELEMENT FOR CONSTRUCTIONAL PURPOSES.

Specification of Letters Patent.

Patented Apr. 1, 1919.

Application filed June 19, 1917. Serial No. 175,629.

* and useful Improved Elements for Constructional Purposes, of which thefollowing is a specification.

This invention relates to improved elements for constructional purposes.

The elements are rigid and of regular geometric lozenge shape, composedof steel or bamboo tubes, bars, rods or the like, connected by headsinto or to which the tubes or the like are screwed, pinned or fastenedaccording to the fixed or movable nature of the construction.

The steel tubes, bars or the like are preferably adopted for importantconstruction, made to last a long time and requirlng a reat resistance,while the bamboo tubes are used for light and rapidly constructedinstallations.

The structures formed of the elements can be mounted and dismounted withgreat celerity, and by the interchangeableness of their elements, can beadapted to various structures according to the circumstances, forinstance the elements having served for the construction of a shed, cansubsequently be employed forbuilding a foot-bridge, an observation orwireless telegraphy post, etc.

The accompanying drawings illustrate the element and various structuresformed from same.

Figure 1 shows the element made of steel tubes mounted in the forks.

Fig. 2 shows the same element in bamboo tubes.

Fig. 3 shows a connector for six elements.

Fig. 4 is a detail of a stool resting direct on the ground or on woodensupports.

Figs. 5, 6 and 7 respectively illustrate various forms of heads.

The element A shown in Fig. 1 is of lozenge shape, adopted by reason ofthe great resistance which it offers; it is composed of steel tubes atwith screw-threaded ends, assembled by forked unions 6.

The assembling of the various elements A is effected by means ofconnecting members 0, which may have a variable number of connections,three in the example shown; the connection is effected by eyes dconnected at e on the member 0.

The shape of the eyes 6 to the conditions of the combination; theyvaries according may be single as shown in Fig. 5, or forked (Fig. 6),or again excentered (Fig. 7.)

The support of the elements on the ground is efiected by means of shoesf fixed direct by pins g or on wooden blocks h resting on the ground;the shoes are provided with the connecting member 0.

The elements A are made of steel tubes, for important structures whichare to support great resistances while for temporary structures bambootubes a may be used for the elements and assembled by metal unions I;mounted in metal forks ,(Fig. 2).

Fig. 3 shows a means of connecting six elements A comprising connections0 connected by plates 7; and six single heads or eyes d towhich theunions b are fixed.

What I claim as my invention and desire to secure by Letters Patent ofthe United States is 1. An element for constructional purposescomprising a metal cross socket member, rods fixed in two oppositesockets of said cross socket to form a longitudinal straight bar, rodsof shorter length than said first mentionedrods fixed in the other twoopposite members of said cross socket member so as to form a cross barto said longitudinal bar, three way socket members fixed at therespective ends of said longitudinal bar and cross bar, rods connectingsaid three way socket members so as to form a frame of substantiallylozenge shape and connecting members on said three way socket members toconnect one element to another, or to the ground.

2. An element for constructional purposes comprising a metal crosssocket member, bamboo rods fixed in two opposite sockets of said crosssocket to form a longitudinal straight bar, bamboo rods of shorterlength than said first mentioned rods fixed in the other two oppositemembers of said cross socket member so as to form a cross bar to saidlongitudinal bar, three way socket members fixed at the respective endsof said lon gitudinal bar and cross bar, bamboo rods connecting saidthree way socket members so as to form a frame of substantially lozengeshape and connecting members on said three way socket members to connectone element to another or to the ground.

3. An element for construction purposes comprising a cross socketmember, longitudinal rods having their inner ends held within thelongitudinal ends of the cross socket member, transverse rods heldwithin the transverse ends of the cross socket member and beingsubstantially shorter than the longitudinal rods and of substantiallythe same length with each other, three way socket members secured to theouter ends of the transverse rods, outer rods having their adjacent endsheld within the opposite ends of the three Way socket members, saidouter rods being arranged in pairs which converge toward the outer endsof the longitudinal rods, and three Way socket members secured to theouter ends of the longitudinal rods and receiving the outer ends of theouter rods. 7 I

4. An element for construction purposes comprising, a central crosssocket member, longitudinal rods of substantiallythe same length havingtheir inner ends held within the longitudinal ends of the cross socketmember, transverse rods having substantially the Qqpien 01 this patentmay be obtained for same length and having their inner ends held sidesof the longitudinal rods and converging toward the outer ends thereof,elements for'securing the inner ends of the outer rods with thetransverse rods, elements for securing the outer ends of the outer rodswith the outer ends of the longitudinal rods, and attaching devices forconnection with said elements. 7 e 7.

In witness whereof I have signed this specification in p the presence oftwo witnesses.
